Find answers to common questions
Budget requirements vary by industry, funnel and competitive intensity, but many advertisers need several thousand dollars per month to collect statistically useful conversion data; smaller budgets can still work if campaigns are tightly targeted to high-intent keywords or remarketing audiences. Prebo Digital designs spend strategies to prioritise profitable channels and scale when unit economics support it.
For eCommerce campaigns the focus is typically on Shopping, dynamic remarketing and ROAS-driven bidding tied to LTV, while B2B emphasises lead quality, account-based targeting, longer attribution windows and CPL/CPA optimisation. In both cases measurement, funnel optimisation and cross-channel attribution are prioritised to ensure spend drives revenue, not just clicks.
Prebo Digital implements clean data pipelines using GA4, Google Tag Manager, and server-side tracking, and ties platform data to on-site conversions and offline events where applicable to reduce attribution bias. Multi-touch attribution models and consolidated reporting are used to align spend with revenue and lifetime value rather than platform-reported last-click metrics.
Prebo Digital offers end-to-end Google Ads services including account audits, campaign strategy and setup (Search, Shopping, Display, Video, Remarketing), bid and budget management, conversion tracking implementation, and ongoing performance optimisations focused on revenue outcomes.
Time to profitability depends on product margins, funnel conversion rates, tracking accuracy and budget; an initial data-collection and learning phase commonly takes 4-8 weeks, with structured optimisation and scaling typically assessed over several months. Prebo Digital focuses on iterative testing and measurement to improve profitability rather than short-term traffic metrics.

Choosing a performance marketing agency is less about traffic and more about sustainable revenue. For US-based founders, marketing directors, and Shopify or WooCommerce store owners, the key question is: will this partner lower customer acquisition cost (CAC), improve lifetime value (LTV), and deliver clean attribution so you can make confident spend decisions? This guide walks through a repeatable process for evaluating agencies against those priorities and explains the technical signals that separate vendor claims from verifiable results.
Before you start outreach, document the metrics that define success for your business (examples for US eCommerce shown):
Assess each prospective agency across technical capability, methodological approach, and business alignment. Weight the areas below based on your priorities.
Evaluate how the agency plans activity across the funnel:
When you review proposals or audits, look for these indicators of a technically mature approach:
| Layer | Client-side | Server-side |
|---|---|---|
| Reliability | Lower (ad blockers, browser limits) | Higher (consolidated events, reduced loss) |
| Attribution clarity | Platform-dependent | Better alignment to revenue |
| Implementation cost | Lower | Moderate to higher |
Practical note: ask agencies for a one-page measurement plan that maps revenue events from your cart to ad-platform conversions - this exposes whether they understand end-to-end attribution.

When you have 3-5 shortlisted agencies, score them against the objective criteria you documented earlier. Use a simple rubric (0-5) across:
Common pricing structures include flat retainers, percentage of ad spend, and performance-for-fee blends. For transparency, prefer retainers with clear scope plus KPIs rather than opaque percent-of-spend models that can incent overspend.
| Model | When it fits | Example cost |
|---|---|---|
| Monthly retainer | Midsize brands needing ongoing strategy | $5,000-$15,000+/mo (varies by scope) |
| % of ad spend | Simple billing but watch incentives | 10%-20% of media spend |
Example: if your monthly ad budget is $50,000 and the agency charges a $7,500 retainer, compare that to a 15% fee ($7,500) but also model the agency’s projected MER improvements - ask for example scenarios in US $ that show net profit impact (estimates only).
